T0 'ALL WHOM IT MAY CONCERN:

Be known that I, JOSEPH A. STANSBURY, of Marion, in the county of Linn, in the State of Iowa, have invented new and useful Improvements in Hannes-Locks; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon.

The nature of my invention consists in providing'a substitute for that partei1 a harness known as 'the hamesstrap, which shall be more durable and substantial than the old style'oi' strap and buckle.

v To enable others skilled in the art to make and use my invention, I will proceed to describe itsconstruction and operation. I

My improved llames-lock is a combination of three castings in malleable iron or other material, constructed in the following manner: The main plate A being curved toit the lower end of the collar, is provided with a suitable hook, with which it may be fastened to oneioi` the hames.' The other end of said plate is provided with two ears, B B, through which. passes a. strong rivet. Said rivet secures between the ears B B the slotted lever C, by passing through the slot D, in the lever (l. To be attaclied'to the other haine is another plate, la", also provided 'with a hook for the purpose. Said plate is also curved to ft the collar in the last-named plate. At

suitable distances from its hook ere one or more holes, each of which is large enough to admit the two ears B B of the plate A.

The manner of operating my improved llames-lock is as follows: Draw the lever G toward the hook on the plate A, so for as the slot and rivet will permit. -Then throw the handle of the lever C over from the hook on the plate A; insert the outerend of the lever-O into one of the holes in the plate Eyat the sannetime'pressing the sadplate E toward the ears B B. Then throw the handle of the lever C back toward the hook on the plate A, which will bringthe plate E into its proper position over the ears B B. Next move the lever C in such a manner that therivet passing through the Vears B B shall be brought into that end of the slot nearest the middle of the lever C. By draught upon the llames, or the natural spring of a collar, the tendency to straighten the curve in the two main plates immediately beneath vthe lever, binds thelever C upon the plate E in such a manner that the said lever may not easily become uni'astened by accident. To unlockthis device, slide the lever C toward the hook on the plate A, Aso far as the slot and rivet willpermit; throw the handle of the lever C over from the said hook ori-the4 plate A, after which the plate E may .be easily disengaged from the ears B B, 'and the homes easily removed. v

Claims.

What I claim as my invention, and desire to secure by Letters Patent, is l. The slotted lever C, when used as and for the purpose specified aud set forth. 2. In combination with the manner of binding the leverC in its proper position, by the tendency of the two curved plates A and E to straighten when under' lengthwise strain, as within substantially described.
